On OSX the linker has a separate framework lookup path which is specified via the `-F` flag. This adds a new kind of `-L` path recognized by the compiler for frameworks to be passed through to the linker. Closes #20259

.SH "EXAMPLES"
|
|
To build an executable from a source file with a main function:
|
|
$ rustc -o hello hello.rs
|
|
|
|
To build a library from a source file:
|
|
